Enter one of the following combos: (s and n),(r and n),(a and n),(a and s and n)
Side LengthNumber of SidesRadiusApothemPerimeter

You entered pentagon which corresponds to the 5 sided polygon so n = 5

Calculate Sum of the Interior Angles:
Interior Angle Sum = (n - 2) x 180°
Interior Angle Sum = (5 - 2) x 180°
Interior Angle Sum = (3) x 180°
Interior Angle sum = 540°

Calculate the number of diagonals of the polygon:
Diagonals =n(n - 3)
2

Diagonals =5(5 - 3)
2

Diagonals =5(2)
2

Diagonals =10
2

Diagonals = 5

Calculate the number of diagonals from one vertex:
1 vertex Diagonals = n - 3
1 vertex Diagonals = 5 - 3
1 vertex Diagonals = 2

Calculate the number of triangles that can be drawn from one vertex:
Triangles = N - 2
Triangles = 5 - 2
Triangles = 3

Construct the formal name of this polygon:
Since the polygon has 5 sides, it is a pentagon
